Regulation of type I IFN responses by deubiquitinating enzyme A in inflammatory bowel diseases

Positive Feedback Regulation of Type I IFN

The Regulation of Immune Responses by DC Derived Type I IFN

Our immune system bears the tremendous task of mounting effective anti-microbial responses whilst maintaining immunoregulatory functions to avoid autoimmunity. In order to quickly respond to pathogens, Dendritic cells (DC) are armed with pattern recognition receptors (PRRs), allowing them to recognize highly conserved pathogen-associated molecular patterns (PAMPs) that are uniquely expressed by...

Epidemiology of Inflammatory Bowel Diseases in Iran and Asia; A Mini Review

The prevalence of inflammatory bowel diseases (IBDs) is set to stabilize in Western Europe and North America, as opposed to its increasing trend in developing countries in Asia. The epidemiology of IBDs in areas where the incidence and prevalence are relatively low provides an opportunity for researchers to determine the unknown aspects of them. In this review article, the PubMed and MEDLINE da...

Regulation of retrotranslocation by p97-associated deubiquitinating enzyme ataxin-3

Misfolded proteins of the endoplasmic reticulum undergo retrotranslocation to enter the cytosol where they are degraded by the proteasome. Retrotranslocation of many substrates requires an ATPase complex consisting of the p97 ATPase and a dimeric cofactor, Ufd1-Npl4. We report that efficient elimination of misfolded ER proteins also involves ataxin-3 (atx3), a p97-associated deubiquitinating en...

Regulation of cellular responses by deubiquitinating enzymes: an update.

The conjugation of ubiquitin as either a monomer or as a chain has long been known to regulate the stability, localisation, trafficking and/or function of many intracellular proteins. However, the recent explosion in our knowledge of the enzymes responsible for the removal of ubiquitin suggests they also play an important role in the regulation of many processes. Here we examine what is known a...
